Using UI-Router in AngularJS to redirect a state to its default substate

I am currently developing a tab-based page that displays data using UI-Router in AngularJs to manage states.

My main goal is to have one default tab open when the page loads. Each tab contains sub tabs, and I want a default sub tab to be open whenever a tab is changed.

During testing, I experimented with the use of the onEnter function where I tried to navigate to the desired substate using $state.go('mainstate.substate');. However, I encountered issues related to loop effects as each call to a substate triggered its parent state, creating an infinite loop.

$stateProvider

.state('main', {
  url: '/main',
  templateUrl: 'main.html',
  onEnter: function($state) {
    $state.go('main.street');
  }
})

.state('main.street', {
  url: '/street',
  templateUrl: 'submenu.html',
  params: {tabName: 'street'}
})

You can view a demo of my progress on Plunker.

Although everything seems to be functioning correctly at the moment, I am still facing the issue of not having the default tab open as intended.

I welcome any suggestions, feedback, or ideas you may have to help me resolve this challenge. Thank you.

Answer №1

Latest Update: Starting from version 1.0, support for redirectTo is now available out of the box.

Read more about it here

If you're facing issues with redirection using .when(), check out this example I created here.

This helpful solution was originally provided in a comment on Stack Overflow (source) and further enhanced by Chris T (originally suggested by yahyaKacem).

For seamless state transition with default redirection, simply extend your main setting like this:

$stateProvider
    .state('main', {
      url: '/main',
      templateUrl: 'main.html',
      redirectTo: 'main.street',
    })

Additionally, add these few lines into your run block:

app.run(['$rootScope', '$state', function($rootScope, $state) {

    $rootScope.$on('$stateChangeStart', function(evt, to, params) {
      if (to.redirectTo) {
        evt.preventDefault();
        $state.go(to.redirectTo, params, {location: 'replace'})
      }
    });
}]);

Easily customize redirection for any state based on your requirements. See it in action here

EDIT: Added an option suggested by @Alec for preserving browser history.

Answer №2

While the solution suggested by Radim did solve the problem at hand, I still needed to keep track of each tab’s sub tab state.

After some exploration, I came across an alternative solution that not only achieved the desired outcome but also maintained the substate for every tab:

All it took was installing ui-router-extras and utilizing the deep state redirect feature:

$stateProvider
  .state('main.street', {
     url: '/main/street',
     templateUrl: 'main.html',
     deepStateRedirect: { default: { state: 'main.street.cloud' } },
  });

Many thanks!

Answer №3

In the latest update of the ui-router, specifically version 1.0, a new feature has been introduced - the redirectTo property. This allows for easy redirection within states. An example implementation is shown below:

.state('Home', {
  redirectTo: 'Home.Dashboard'
})

Answer №4

With the introduction of ui-router version 1.0, a new default hook utilizing IHookRegistry.onBefore() has been implemented. An example showcasing this feature can be found in the Data Driven Default Substate section at http://angular-ui.github.io/ui-router/feature-1.0/interfaces/transition.ihookregistry.html#onbefore

// State declaration
{
  name: 'home',
  template: '<div ui-view/>',
  defaultSubstate: 'home.dashboard'
}

var criteria = {
  to: function(state) {
    return state.defaultSubstate != null;
  }
}
$transitions.onBefore(criteria, function($transition$, $state) {
  return $state.target($transition$.to().defaultSubstate);
});

Answer №5

app.config(function($stateProvider,$urlRouterProvider){

    $urlRouterProvider.when("/home","/home/sub-home");

    })

Answer №6

When seeking guidance on how to implement a straightforward redirect for a state without access to the new router, it can present a challenge. This situation recently occurred with me.

If feasible, following @bblackwo's suggestion is ideal:

$stateProvider.state('A', {
  redirectTo: 'B',
});

If this option is not available, manually redirecting it is an alternative:

$stateProvider.state('A', {
  controller: $state => {
    $state.go('B');
  },
});

I trust this information proves to be useful!
